1.1 benno 512: <ul>
513: <li>Potentially incompatible changes.
1.14 benno 514: <ul>
515:
516: <li>For FIDO/U2F support, OpenSSH recommends the use of libfido2
517: 1.5.0 or greater. Older libraries have limited support at the expense
518: of disabling particular features. These include resident keys, PIN-
519: required keys and multiple attached tokens.
520:
521: <li><a href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a>:
522: the format of the attestation information optionally recorded when a
523: FIDO key is generated has changed. It now includes the authenticator
524: data needed to validate attestation signatures.
525:
526: <li>The API between OpenSSH and the FIDO token middleware has
527: changed and the SSH_SK_VERSION_MAJOR version has been incremented as a
528: result. Third-party middleware libraries must support the current API
529: version (7) to work with OpenSSH 8.4.
530:
531: <li>The portable OpenSSH distribution now requires automake to
532: rebuild the configure script and supporting files. This is not
533: required when simply building portable OpenSSH from a release tar
534: file.
535:
536: </ul>
1.1 benno 537: <li>New Features
1.14 benno 538: <ul>
539:
540: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>, <a
541: href="https://man.openbsd.org/ssh-keygen">ssh-keygen">ssh-keygen(1)</a>:
542: support for FIDO keys that require a PIN for each use. These keys may
543: be generated using ssh-keygen using a new "verify-required" option.
544: When a PIN-required key is used, the user will be prompted for a PIN
545: to complete the signature operation.
546:
547: <li><a href="https://man.openbsd.org/sshd">sshd(8)</a>:
548: authorized_keys now supports a new "verify-required" option to require
549: FIDO signatures assert that the token verified that the user was
550: present before making the signature. The FIDO protocol supports
551: multiple methods for user-verification, but currently OpenSSH only
552: supports PIN verification.
553:
554: <li><a href="https://man.openbsd.org/sshd">sshd(8)</a>, <a
555: href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a>: add
556: support for verifying FIDO webauthn signatures. Webauthn is a standard
557: for using FIDO keys in web browsers. These signatures are a slightly
558: different format to plain FIDO signatures and thus require explicit
559: support.
560:
561: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>: allow some
562: keywords to expand shell-style ${ENV} environment variables. The
563: supported keywords are CertificateFile, ControlPath, IdentityAgent and
564: IdentityFile, plus LocalForward and RemoteForward when used for Unix
565: domain socket paths.
566:
567: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>, <a
568: href="https://man.openbsd.org/ssh-agent">ssh-agent(1)</a>: allow some
569: additional control over the use of ssh-askpass via a new
570: $SSH_ASKPASS_REQUIRE environment variable, including forcibly enabling
571: and disabling its use.
572:
573: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>: allow <a
574: href="https://man.openbsd.org/ssh_config">ssh_config(5)</a>'s
575: AddKeysToAgent keyword accept a time limit for keys in addition to its
576: current flag options. Time- limited keys will automatically be removed
577: from ssh-agent after their expiry time has passed.
578:
579: <li><a href="https://man.openbsd.org/scp">scp(1)</a>, <a
580: href="https://man.openbsd.org/sftp">sftp(1)</a>: allow the -A flag to
581: explicitly enable agent forwarding in scp and sftp. The default
582: remains to not forward an agent, even when ssh_config enables it.
583:
584: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>: add a '%k'
585: TOKEN that expands to the effective HostKey of the destination. This
586: allows, e.g., keeping host keys in individual files using
587: "UserKnownHostsFile ~/.ssh/known_hosts.d/%k".
588:
589: <li><a href="https://man.openbsd.org/ssh(1): add %-TOKEN,
590: environment variable and tilde expansion to the UserKnownHostsFile
591: directive, allowing the path to be completed by the configuration.
592:
593: <li><a href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a>:
594: allow "ssh-add -d -" to read keys to be deleted from stdin.
595:
596: <li><a href="https://man.openbsd.org/sshd">sshd(8)</a>: improve
597: logging for MaxStartups connection throttling. sshd will now log when
598: it starts and stops throttling and periodically while in this state.
599:
600:
601: </ul>
1.1 benno 602: <li>Bugfixes
1.14 benno 603: <ul>
604:
605: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>, <a
606: href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a>: better
607: support for multiple attached FIDO tokens. In cases where OpenSSH
608: cannot unambiguously determine which token to direct a request to, the
609: user is now required to select a token by touching it. In cases of
610: operations that require a PIN to be verified, this avoids sending the
611: wrong PIN to the wrong token and incrementing the token's PIN failure
612: counter (tokens effectively erase their keys after too many PIN
613: failures).
614:
615: <li><a href="https://man.openbsd.org/sshd">sshd(8)</a>: fix Include
616: before Match in <a
617: href="https://man.openbsd.org/sshd_config">sshd_config(5)</a>.
618:
619: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>: close
620: stdin/out/error when forking after authentication completes ("ssh -f
621: ...").
622:
623: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>, <a
624: href="https://man.openbsd.org/sshd">sshd(8)</a>: limit the amount of
625: channel input data buffered, avoiding peers that advertise large
626: windows but are slow to read from causing high memory consumption.
627:
628: <li><a href="https://man.openbsd.org/ssh-agent">ssh-agent(1)</a>:
629: handle multiple requests sent in a single write() to the agent.
630:
631: <li><a href="https://man.openbsd.org/sshd">sshd(8)</a>: allow <a
632: href="https://man.openbsd.org/sshd_config">sshd_config(5)</a> longer than 256k
633:
634: <li><a href="https://man.openbsd.org/sshd">sshd(8)</a>: avoid
635: spurious "Unable to load host key" message when sshd load a private
636: key but no public counterpart
637:
638: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>: prefer the
639: default hostkey algorithm list whenever we have a hostkey that matches
640: its best-preference algorithm.
641:
642: <li><a href="https://man.openbsd.org/sshd">sshd(1)</a>: when
643: ordering the hostkey algorithms to request from a server, prefer
644: certificate types if the known_hosts files contain a key marked as a
645: @cert-authority;
646:
647: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>: perform host
648: key fingerprint comparisons for the "Are you sure you want to continue
649: connecting (yes/no/[fingerprint])?" prompt with case sensitivity.
650:
651: <li><a href="https://man.openbsd.org/sshd">sshd(8)</a>: ensure that
652: address/masklen mismatches in sshd_config yield fatal errors at daemon
653: start time rather than later when they are evaluated.
654:
655: <li><a href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a>:
656: ensure that certificate extensions are lexically sorted. Previously if
657: the user specified a custom extension then the everything would be in
658: order except the custom ones.
659:
660: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>: also compare
661: username when checking for JumpHost loops.
662:
663: <li><a href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a>:
664: preserve group/world read permission on known_hosts files across runs
665: of "ssh-keygen -Rf /path". The old behaviour was to remove all rights
666: for group/other.
667:
668: <li><a href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a>:
669: Mention the [-a rounds] flag in the ssh-keygen manual page and
670: usage().
671:
672: <li><a href="https://man.openbsd.org/sshd">sshd(8)</a>: explicitly construct path to ~/.ssh/rc rather than
673: relying on it being relative to the current directory, so that it
674: can still be found if the shell startup changes its directory.
675:
676: <li><a href="https://man.openbsd.org/sshd">sshd(8)</a>: when
677: redirecting sshd's log output to a file, undo this redirection after
678: the session child process is forked(). Fixes missing log messages when
679: using this feature under some circumstances.
680:
681: <li><a href="https://man.openbsd.org/sshd">sshd(8)</a>: start
682: ClientAliveInterval bookkeeping before first pass through select()
683: loop; fixed theoretical case where busy sshd may ignore timeouts from
684: client.
685:
686: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>: only reset the
687: ServerAliveInterval check when we receive traffic from the server and
688: ignore traffic from a port forwarding client, preventing a client from
689: keeping a connection alive when it should be terminated.
690:
691: <li><a href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a>:
692: avoid spurious error message when ssh-keygen creates files outside
693: ~/.ssh
694:
695: <li><a
696: href="https://man.openbsd.org/sftp-client">sftp-client(1)</a>: fix
697: off-by-one error that caused sftp downloads to make one more
698: concurrent request that desired. This prevented using <a
699: href="https://man.openbsd.org/sftp">sftp(1)</a> in unpipelined
700: request/response mode, which is useful when debugging.
701:
702: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>, <a
703: href="https://man.openbsd.org/sshd">sshd(8)</a>: handle EINTR in
704: waitfd() and timeout_connect() helpers.
705:
706: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>, <a
707: href="https://man.openbsd.org/ssh-keygen">ssh-keygen(1)</a>: defer
708: creation of ~/.ssh until we attempt to write to it so we don't leave
709: an empty .ssh directory when it's not needed.
710:
711: <li><a href="https://man.openbsd.org/ssh">ssh(1)</a>, <a
712: href="https://man.openbsd.org/sshd">sshd(8)</a>: fix multiplier when
713: parsing time specifications when handling seconds after other units.

899: Copy 'boot' and 'bsd.rd' to a Mach or UniOS partition, and boot the bootloader
900: from the PROM, and then bsd.rd from the bootloader.
901: Refer to the instructions in INSTALL.luna88k for more details.

903: <h3>OpenBSD/macppc:</h3>
904:
905: <p>
906: Burn the image from a mirror site to a CDROM, and power on your machine
907: while holding down the <i>C</i> key until the display turns on and
908: shows <i>OpenBSD/macppc boot</i>.
909:
910: <p>
911: Alternatively, at the Open Firmware prompt, enter <i>boot cd:,ofwboot
912: /6.8/macppc/bsd.rd</i>
913:
914: <h3>OpenBSD/octeon:</h3>
915:
916: <p>
917: After connecting a serial port, boot bsd.rd over the network via DHCP/tftp.
918: Refer to the instructions in INSTALL.octeon for more details.

929: To install, burn cd68.iso on a CD-R, put it in the CD drive of your
930: machine and select <i>Install System Software</i> from the System Maintenance
931: menu. Indigo/Indy/Indigo2 (R4000) systems will not boot automatically from
932: CD-ROM, and need a proper invocation from the PROM prompt.
933: Refer to the instructions in INSTALL.sgi for more details.
934:
935: <p>
936: If your machine doesn't have a CD drive, you can setup a DHCP/tftp network
937: server, and boot using "bootp()/bsd.rd.IP##" using the kernel matching your
938: system type. Refer to the instructions in INSTALL.sgi for more details.
939:
940: <h3>OpenBSD/sparc64:</h3>
941:
942: <p>
943: Burn the image from a mirror site to a CDROM, boot from it, and type
944: <i>boot cdrom</i>.
945:
946: <p>
947: If this doesn't work, or if you don't have a CDROM drive, you can write
948: <i>floppy68.fs</i> or <i>floppyB68.fs</i>
949: (depending on your machine) to a floppy and boot it with <i>boot
950: floppy</i>. Refer to INSTALL.sparc64 for details.
951:
952: <p>
953: Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
954: will most likely fail.
955:
956: <p>
957: You can also write <i>miniroot68.fs</i> to the swap partition on
958: the disk and boot with <i>boot disk:b</i>.
959:
960: <p>
961: If nothing works, you can boot over the network as described in INSTALL.sparc64.

977: <h3>Notes about the source code</h3>
978: <p>
979: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
980: This file contains everything you need except for the kernel sources,
981: which are in a separate archive.
982: To extract:
983: <blockquote><pre>
984: # <kbd>mkdir -p /usr/src</kbd>
985: # <kbd>cd /usr/src</kbd>
986: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
987: </pre></blockquote>
988: <p>
989: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
990: This file contains all the kernel sources you need to rebuild kernels.
991: To extract:
992: <blockquote><pre>
993: # <kbd>mkdir -p /usr/src/sys</kbd>
994: # <kbd>cd /usr/src</kbd>
995: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
996: </pre></blockquote>
997: <p>
998: Both of these trees are a regular CVS checkout. Using these trees it
999: is possible to get a head-start on using the anoncvs servers as
1000: described <a href="anoncvs.html">here</a>.
1001: Using these files
1002: results in a much faster initial CVS update than you could expect from
1003: a fresh checkout of the full OpenBSD source tree.

1010: <p>
1011: A ports tree archive is also provided. To extract:
1012: <blockquote><pre>
1013: # <kbd>cd /usr</kbd>
1014: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1015: </pre></blockquote>
1016: <p>
1017: Go read the <a href="faq/ports/index.html">ports</a> page
1018: if you know nothing about ports
1019: at this point. This text is not a manual of how to use ports.
1020: Rather, it is a set of notes meant to kickstart the user on the
1021: OpenBSD ports system.
1022: <p>
1023: The <i>ports/</i> directory represents a CVS checkout of our ports.
1024: As with our complete source tree, our ports tree is available via
1025: <a href="anoncvs.html">AnonCVS</a>.
1026: So, in order to keep up to date with the -stable branch, you must make
1027: the <i>ports/</i> tree available on a read-write medium and update the tree
1028: with a command like:
1029: <blockquote><pre>
1030: # <kbd>cd /usr/ports</kbd>
1031: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_8</kbd>
1032: </pre></blockquote>
1033: <p>
1034: [Of course, you must replace the server name here with a nearby anoncvs
1035: server.]
1036: <p>
1037: Note that most ports are available as packages on our mirrors. Updated
1038: ports for the 6.8 release will be made available if problems arise.
1039: <p>
1040: If you're interested in seeing a port added, would like to help out, or just
1041: would like to know more, the mailing list
1042: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
